Is saturated vapor. Compression in the compressor is not isentropic with the refrigerant leaving the compressor and entering the condenser at 60o C and 1000kPa. Refrigerant leaving the condenser and entering the expansion valve is saturated liquid. Find the following: (a) power consumption in the compressor (kW), (b) rate of heat addition to the evaporator (kW), (c) condenser heat rejection rate (kW), (d) cycle coefficient of performance, (e) compressor isentropic efficiency, (f) entropy generation rate in the expansion valve (kW/K), and (g) the irreversibility rate in the expansion valve in kW if the ambient temperature i
